Description

Method and device for transmitting uplink control information UCI

The present application claims the priority of the Chinese Patent Application, filed on Sep. 29, 2016, filed Jan. In this application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and a device for transmitting uplink control information (UPI).

Background technique

The existing Long Term Evolution (LTE) Frequency Division Duplex (FDD) system uses a frame structure (Frame Structure type 1, FS1 for short), and its structure is shown in FIG. 1 . In the FDD system, the uplink and downlink transmissions use different carrier frequencies, and both the uplink and downlink transmissions use the same frame structure. On each carrier, a 10ms length radio frame contains 10 1ms subframes, and each subframe is divided into two 0.5ms long slots. The transmission time interval (TTI) of the uplink and downlink data transmission is 1 ms.

The existing LTE Time Division Duplex (TDD) system uses a Frame Structure type 2 (FS2), as shown in FIG. 2 . In a TDD system, uplink and downlink transmissions use different subframes or different time slots on the same frequency. Each 10 ms radio frame in FS2 consists of two 5 ms half frames, each of which contains five subframes of 1 ms length. The sub-frames in FS2 are classified into three types: downlink sub-frames, uplink sub-frames, and special sub-frames. Each special sub-frame consists of a Downlink Pilot Time Slot (DwPTS) and a Guard Period (GP). And the Uplink Pilot Time Slot (UpPTS) is composed of three parts. Each field includes at least one downlink subframe and at least one uplink subframe, and at most one special subframe.

In the prior art, the Scheduling Request (SR) and the Channel State Information (CSI) are transmitted in units of subframes, and the configuration of the reporting period and the offset value are also in the sub-frame. The frame is in units. With the development of mobile communication service requirements, higher user plane delay performance requirements are defined for future mobile communication systems. One of the main methods for shortening the user delay performance is to reduce the transmission time interval (TTI) length. Therefore, the subframe structure defined in the existing LTE mechanism includes a plurality of short TTIs shorter than 1 ms. In a short TTI transmission, the uplink supports a short physical uplink shared channel (sPUSCH) and a short physical uplink control channel (sPUCCH), and the sPUCCH can be used to carry at least a downlink using a short TTI. Transmitted ACK/NACK feedback information. The length of the short TTI can be 2, 3, 4, 7 OFDM or SC-FDMA The symbol, of course, does not exclude the case where the number of other symbols does not exceed 14 or the length of the time domain does not exceed 1 ms.

Since existing channels and UCI transmissions are defined in units of subframes, there is no clear way to perform UCI transmission in short TTIs.

A method for transmitting uplink control information UCI according to an embodiment of the present invention is described in detail below by using the following three specific embodiments.

Embodiment 1: This embodiment takes SR feedback as an example, and describes a short TTI of 2 symbol lengths as an example. It is assumed that the feedback period and the subframe offset value of the SR are configured in units of subframes, as shown in Table 1, wherein the sr-ConfigIndex I _SR is a pre-configured parameter of the high layer signaling, and the SR feedback period SR _{PERIODICITY is} obtained according to the parameter lookup table. And the SR subframe offset value N _{OFFSET, SR} , determined according to the feedback period and the offset value according to the formula

The subframe is a feedback subframe of the SR, where n _f is the radio frame number, n _s is the slot number, and mod is the modulo operation.

Table 1: SR Period and Subframe Offset Configuration

(SR periodicity and subframe offset configuration)

1) The base station determines the feedback subframe of the SR, and determines a corresponding _ISR value, which is configured to the terminal by using high layer signaling.

2) The base station configures or pre-arranges, by the terminal, one or more short TTI positions in each feedback subframe to be the short TTI position where the SR transmission is located, for example, assume the first and fourth in each feedback subframe. The short TTI is a short TTI location for transmitting the SR. As shown in FIG. 5A and FIG. 5B, of course, only one short TTI location may be defined. For example, the first short TTI is the short TTI location where the SR transmission is located, etc., in this embodiment, two A short TTI transmission SR is taken as an example for description. Other situations are similar, and are not illustrated here.

3) The terminal receives the high layer signaling, obtains the _ISR value, and obtains the feedback subframe of the SR according to the value of the table 1; further determines one of each feedback subframe according to the configuration signaling of the base station or the pre-arrangement with the base station. Or a plurality of short TTI locations are short TTI locations where the SR transmission is located, for example, assuming that the first and fourth short TTIs in each feedback subframe are short TTI locations for transmitting SRs;

4) The terminal determines whether it is necessary to transmit the SR in the short TTI position for SR transmission in the feedback subframe of the SR (for example, there is a positive SR (positive SR) or transmitted together with other UCI, the same below). If it is determined that it is not required, the terminal does not transmit the SR in the short TTI position in the feedback subframe; if it is determined to be necessary, the terminal transmits the SR through the sPUCCH or sPUSCH at the short TTI position in the feedback subframe.

A. If the sPUSCH transmission is supported by the sPUCCH and the sPUSCH transmission or the short TTI location of the transmission SR does not exist, the terminal transmits the SR through the sPUCCH.

Specifically, if only the SR exists in the short TTI location of the transmitting SR, the terminal transmits the SR through the sPUCCH on the s PUCCH resource corresponding to the SR; if there are other UCIs in the short TTI location of the transmitting SR, such as ACK/NACK (including Short DOWN (DL) TTI ACK/NACK and/or 1ms DL TTI ACK/NACK), then the terminal is The SR and ACK/NACK are simultaneously transmitted through the sPUCCH on the sPUCCH resource corresponding to the ACK/NACK.

B. If the sPUCCH and the sPUSCH are not supported for simultaneous transmission, and the sPUSCH transmission exists in the short TTI location of the transmission SR, the terminal sends the SR through the sPUSCH (as a Buffer Status Report (BSR) and the data is sent together);

5) The base station blindly detects the SR in the short TTI position for transmitting the SR in the determined SR feedback subframe, as follows:

A. If the sPUCCH and sPUSCH are supported for simultaneous transmission or there is no sPUSCH transmission in the short TTI location of the transmission SR (ie, the base station does not schedule the sPUSCH in the short TTI), the base station detects the SR in the sPUCCH.

Specifically, if only the SR exists in the short TTI location of the transmission SR, the base station detects the SR on the s PUCCH resource corresponding to the SR; if there are other UCIs in the short TTI location of the transmission SR, such as ACK/NACK (including the short DL) The ACK/NACK of the TTI and/or the ACK/NACK of the 1ms DL TTI, the base station simultaneously detects the SR and the ACK/NACK on the s PUCCH resource corresponding to the ACK/NACK;

B. If sPUCCH and sPUSCH are not supported for simultaneous transmission, and there is sPUSCH transmission in the short TTI position of the transmission SR (ie, the base station schedules sPUSCH in the short TTI), the base station detects the SR in the sPUSCH (as the BSR is sent together with the data) ).

If the base station does not detect the sPUSCH in the short TTI, it is determined that the terminal has lost the scheduling signaling of the sPUSCH; the base station may further detect the SR by using the sPUCCH, the same procedure as that detected on the sPUCCH.

Embodiment 2: This embodiment is still described by taking SR feedback as an example and taking a short TTI of 2 symbol lengths as an example. It is assumed that the feedback period and the subframe offset value of the SR are configured in units of subframes. For details, refer to the related description in Embodiment 1.

2) The terminal receives the high layer signaling, obtains the _ISR value, and obtains the feedback subframe of the SR according to the value of Table 1.

3) The terminal determines whether it is necessary to transmit the SR in the feedback subframe of the SR (for example, there is a positive SR or simultaneous transmission with other UCIs), if it is determined not to be, the SR is not transmitted, if it is determined to be necessary:

A. When it is determined that the sPUCCH transmission is performed (for example, there is no sPUSCH scheduling, or there is sPUSCH scheduling and sPUCCH and sPUSCH are simultaneously transmitted), the terminal determines, according to configuration signaling or a predetermined agreement, in the first sTTI position in the feedback subframe. The SR is transmitted through the sPUCCH; as shown in FIGS. 6A and 6B.

Specifically, if only the SR exists in the feedback subframe, the terminal transmits the SR through the sPUCCH on the s PUCCH resource corresponding to the SR; if there are other UCIs in the feedback subframe, such as ACK/NACK (including the ACK of the short DL TTI) NACK and/or ACK/NACK of 1ms DL TTI), the terminal simultaneously transmits SR and ACK/NACK through the sPUCCH on the s PUCCH resource corresponding to the ACK/NACK.

B. When it is determined that the sPUSCH transmission is performed (for example, there is sPUSCH scheduling and does not support simultaneous transmission of sPUCCH and sPUSCH), the terminal determines the first sPUSCH in the feedback subframe according to configuration signaling or a pre-agreed (the first sPUSCH may The sPUSCH is not transmitted in the first sTTI in the feedback subframe. In this embodiment, only the sPUSCH transmission exists in the first sTTI, and the location of the sPUSCH in the current feedback subframe is taken as an example in FIG. 6A and FIG. 6B. Depending on the base station scheduling, it is also possible to transmit the SR in the second short TTI or the subsequent short TTI.

An implementation manner is: the terminal always selects the first sPUSCH in the feedback subframe for transmitting the SR, and if the terminal aggregates multiple carriers, the terminal selects the first one of the multiple feedback carriers in the feedback subframe. The SR is transmitted in the sPUSCH as shown in FIGS. 7A and 7B.

Another implementation manner is: if there is sPUSCH transmission on the PCC in the feedback subframe, the terminal transmits the SR in the sPUSCH on the PCC, and if there are multiple sPUSCHs in the feedback subframe on the PCC, the terminal is in the first The SR is transmitted in the sPUSCH. If there is no sPUSCH transmission on the PCC in the feedback subframe, the terminal transmits the SR in the sPUSCH on the SCC with the smallest carrier number in the sPUSCH transmission in the feedback subframe, if the SCC is in the SCC If there are multiple sPUSCHs in the feedback subframe, the terminal transmits the SR in the first sPUSCH, as shown in FIG. 8A and FIG. 8B.

4) The base station blindly detects the SR in the determined feedback subframe of the SR, as follows:

A. When the base station determines that the SR in the feedback subframe is transmitted in the sPUCCH (for example, there is no sPUSCH scheduling, or there is sPUSCH scheduling and supports simultaneous transmission of sPUCCH and sPUSCH), the base station determines the feedback subframe according to configuration signaling or a pre-agreed. The first sTTI position in the sPUCCH detects the SR.

Specifically, if it is determined that only the SR exists in the feedback subframe, the base station detects the SR by using the sPUCCH on the s PUCCH resource corresponding to the SR; if there are other UCIs in the feedback subframe, such as ACK/NACK (including the ACK of the short DL TTI) /NACK and/or ACK/NACK of 1ms DL TTI), the base station simultaneously detects SR and ACK/NACK through the sPUCCH on the s PUCCH resource corresponding to the ACK/NACK.

B. When the base station determines to transmit by using the sPUSCH (for example, there is sPUSCH scheduling and does not support simultaneous transmission of the sPUCCH and the sPUSCH), the base station determines, according to configuration signaling or a predetermined agreement, the first sPUSCH in the feedback subframe (ie, the base station The first sPUSCH scheduled is not necessarily the acquisition SR transmitted in the first sTTI in the subframe.

An implementation manner is: the base station always selects the first sPUSCH detection SR in the feedback subframe, and if the terminal aggregates multiple carriers, the base station selects the first sPUSCH detection in the feedback subframe on multiple carriers. SR;

Another implementation manner is: if there is sPUSCH transmission on the PCC in the feedback subframe (that is, the base station schedules sPUSCH, the same below), the base station detects the SR in the sPUSCH on the PCC, if the PCC is in the feedback subframe. If there are multiple sPUSCHs, the base station detects the SR in the first sPUSCH. If there is no sPUSCH transmission on the PCC in the feedback subframe, the base station has the sPUSCH transmitted on the SCC with the smallest carrier number in the feedback subframe. The SR is detected in the sPUSCH. If there are multiple sPUSCHs in the feedback subframe on the SCC, the base station detects the SR in the first sPUSCH.

If the base station does not detect the sPUSCH in the short TTI transmitted by the first sPUSCH, the terminal determines that the terminal has lost the scheduling signaling of the sPUSCH (the terminal side is equivalent to the second sPUSCH scheduled by the base station as the first). The base station may further attempt to acquire the SR in the next scheduled sPUSCH.

Embodiment 3: This embodiment still takes SR feedback as an example, and describes a short TTI of 2 symbol lengths as an example. Assuming that the feedback period and offset value of the SR are configured in units of short TTIs of 2 symbols, a table format similar to Table 1 can be defined to represent periods and offsets in units of short TTI, which are determined according to the feedback period and the offset value. The feedback of the SR is short TTI position.

1) The base station determines the feedback short TTI position of the SR. For example, if it is determined that there is one short TTI every 3 short TTIs, the SR can be transmitted, and the offset value is 1, that is, the calculation starts from the second short TTI, and as shown in FIG. 9A. And the short TTI position shown in FIG. 9B is used to transmit the SR; the base station can notify the terminal of the relevant configuration through high layer signaling.

2) The terminal receives the high layer signaling, determines that the feedback short TTI position of the SR is calculated from the second short TTI, and the short TTI exists for every three short TTIs to transmit the SR, and obtains the short TTI as shown in FIG. 9A and FIG. 9B. The location is used to transport the SR.

3) The terminal determines whether it is necessary to transmit the SR in the short TTI position of the SR transmission (for example, there is a positive SR or transmits with other UCI), if it is determined that it is not needed, the terminal does not transmit the SR, and if it is determined that the terminal is in the transmission SR The process of transmitting the SR in the short TTI position is the same as the process of transmitting the SR in the short TTI position of the transmission SR in a feedback subframe in Embodiment 1, and details are not described herein again.

4) The base station blindly detects the SR at the short TTI position of the determined transmission SR, and the process of detecting the SR at the short TTI position of each transmission SR is the same as the short TTI position of the transmission SR of the base station in one feedback subframe in Embodiment 1. The process of detecting the SR is the same and will not be described again.

It should be noted that, in the foregoing embodiment, the short TTI transmission of only two symbols is taken as an example, and the short TTI transmission of other symbol lengths is the same, and the present invention is not illustrated by way of example; the short TTI in one subframe is not divided. Other divisions other than the above embodiments are excluded. In the foregoing embodiment, only the SR transmission is taken as an example, and the transmission of the periodic CSI is the same, and the present invention is not illustrated by way of example. In the above embodiment, one subframe is used as an example of the whole upper-layer behavior. When a partial time domain position in one subframe is uplink (such as a special subframe) or a discontinuous uplink subframe (such as TDD), the processing manner is similar. The present invention will not be exemplified one by one.
